Is there a way to embed Worpress on your website? Currently, I have Blogger embedded in an I-frame but I would really like to switch to WP.

I want my site to look something like this: (http://www.seductivesiren.com) (if you look at her froggy skin, that's the look I am going for)

So, can it be embedded in my site or do I have to kind of build my site around the WP blog? I would prefer not to have the suffix of ".PHP".

Thanks for any help you may be able to offer!

You'll have to have at least one page with the .php ending, the wordpress blog needs that in order for it to work.
You could use an iframe, it would probably make it easier to customize your template then (some people find it difficult to work their layout around all the wordpress codes and such). A PHP include is also an option, but the page you're including the blog on would have to have the .php ending. Your include would simply have the wordpress-specific codes, although I think there are some extra header codes wou would have to stick in your main page separately.
